Apple IIgs and HFS partitions

This is probably a bit of noob here, but I discovered I could run programs off an HFS partition!

Is this an unwise practice? Or perfectly ok?

Apple IIc RAM Repair

So I've got a IIc here, starts up with random characters on screen and the built in self test throws out RAM ZP 01000000. I went ahead and replaced RAM #MRD6 and now it shows RAM 00100000. I found this strange and piggybacked MRD5, resulted in RAM ZP 10000000 (MRD7), piggybacked that one too and it just goes up the ladder into the auxiliary bank with *RAM 0.... .

Any suggestions? Should I suspect the MMU?

inexpensive FPGA-based 6502 CPU replacement and Disk II emulator

A few weeks ago, I went looking for an in-circuit emulator/debugger for my trusty old Apple II and stumbled across a project called "ICE-T65"

http://www.stardot.org.uk/forums/viewtopic.php?f=44&t=9655

The hardware is a small FPGA mounted on a 40-pin board that has a similar form-factor to a 6502 processor, and with the right software, can be used as a pin-compatible, plug-in replacement for a 6502. Installation is as simple as popping out the CPU and putting this board in it's place.

My goal then became to add a virtual Disk II interface into the FPGA code. Initially, I was thinking of using an SD card for backing store, but then decided it would be more flexible if I added a network interface and allowed it to boot disk images over the network. (i.e. you can use this to boot a real physical Apple II from a disk image hosted on a web site)

Apple II Serial Number Registry

Hi guys,

Triggered by a conversation in another recent thread, I have thrown together an Apple II serial registry page. I was able to modify my popular C64 registry without too much trouble.

How to test a Serial Interface Card?

Is there a diagnostics tool which can test the Serial Interface Card on an Apple IIe? Or any other way to confirm if the card and the Roms are properly functioning?

Any suggestions would be appreciated Smile
